Prescription Patterns in Management of Heart Failure and Its Association With Readmissions: A Retrospective Analysis

BackgroundThe American Heart Association/American College of Cardiology/Heart Failure Society of America recently added sodium-glucose cotransporter-2 inhibitors in addition to renin–angiotensin–aldosterone system inhibitors, beta-blockers, and mineralocorticoid receptor antagonists to form the 4 pillars of guideline-directed medical therapy (GDMT) for the management of heart failure with reduced ejection fraction (HFrEF). Despite strong evidence suggesting improved outcomes with inpatient initiation of GDMT at target doses, significant lag has been noted in prescription practices. We sought to study GDMT prescription rates in patients with HFrEF at the time of hospital discharge and evaluate its association with various patient characteristics and all-cause readmission rates. Methods and ResultsWe used a modified version of Heart Failure Collaboratory (HFC) score to characterize patients into 2 groups (those with an HFC score of <3 and an HFC score of ≥3) and to examine various socioeconomic and biomedical factors affecting GDMT prescription practices. Out of the eligible patients, the prescription rates for beta-blockers was 77.9%, renin–angiotensin–aldosterone system inhibitor was 70.3%, and mineralocorticoid receptor antagonists was 41%. Furthermore, prescription rates for sacubitril/valsartan was 27.7% and sodium-glucose cotransporter-2 inhibitors was 17%. Only 1% of patients had an HFC score of 9 (drugs from all 4 classes at target doses). Patients of black ethnicity, those admitted on teaching service and those with HFrEF as the primary cause of admission were more likely to have an HFC of ≥3 at discharge. An HFC of ≥3 was associated with lower rates of 1-month all-cause readmissions. ConclusionsConsistent with the prior research, our data show significant gaps in prescription of GDMT in HFrEF. Further implementation research should be done to improve GDMT prescription during inpatient stay.

Best practices guidelines in the postoperative management of patients who underwent cervical and lumbar fusions.

There is a lack of standardization in spine surgery in particular, as relates to postoperative care for the most common spine procedures such as cervical and lumbar fusions. The goal of this study was to develop a standardized postoperative treatment protocol for common spine procedures such as cervical and lumbar fusion to reduce unnecessary visits, imaging studies, and create a standard for all spine surgeons to adhere while maintaining quality. We developed a best practices protocol (BPP) for postoperative spine care for anterior cervical diskectomy and fusion (ACDF) and posterior lumbar interbody fusion (PLIF). We compared outcome to retrospective controls (pre-BPP) and a national database [Quality Outcomes Database (QOD)/American Spine Registry (ASR)]. Pre-BPP retrospective controls (n=1,010) were compared to patients enrolled in BPP (n=750). BPP reduced postoperative visits (POV) from 2,201 to 1,061 (52%). Total additional imaging studies computed tomography (CT) and magnetic resonance imaging (MRI) beyond standard X-ray were reduced from 192 studies to 57 (70%); 53% for lumbar fusion and 67% for cervical fusion. Comparing pre-BPP to BPP groups for complications, the number of adverse events was reduced by 52% overall; 45% for lumbar fusion, and 62% for cervical fusion. A subset of BPP patients (n=450) with available data were compared to a national registry QOD and ASR where lumbar and cervical fusion patients showed comparable less lengths of stay, lower 3-month complication rates and lower readmission rates. This is one of the first studies to standardize postoperative spine care as a first step towards creating uniformly accepted models for value-based care (VBC) in spine surgery.

Vitamin D deficiency and its impact on outcomes in myocardial infarction patients: a prospective observational study

Objectives: Vitamin D deficiency has been linked to cardiovascular diseases, but its impact on outcomes in myocardial infarction (MI) patients remains unclear. This study investigated the relationship between serum vitamin D levels and short-term and medium-term outcomes in patients with myocardial infarction. Ischemic heart diseases (IHD) are the most common cause of death in the world. Identifying risk factors and predictors can play a critical role in identifying high-risk people in screenings, identifying high-risk patients during admission to the hospital, and adjusting these risk factors in patients to improve prognosis. Methods: This prospective observational study was conducted on 212 patients diagnosed with myocardial infarction at Seyed al-Shohada Hospital in Urmia, Iran. Having been admitted, the patients had their serum vitamin D levels measured using the same blood sample for routine tests. Levels of vitamin D were categorized as normal (&gt;30 ng/ml), insufficient (21-29 ng/ml), or deficient (&lt;20 ng/ml). The patient's files provided the demographic, clinical, and biomedical information, echocardiography, and angiography data. The patients were followed for at least six months post-MI, with a maximum follow-up of 11 months. Follow-up occurred through monthly phone calls and outpatient clinic visits as needed. Primary outcomes included in-hospital complications (such as death, significant bleeding, acute pulmonary edema, cardiogenic shock, and arrhythmias), cardiac readmissions, and mortality. Logistic regression and Cox regression analyses were used to examine the connection between outcome variables and vitamin D levels, adjusting for potential confounders including age, gender, blood pressure, diabetes, blood lipids, creatinine, disease severity (SYNTAX score*), and left ventricular ejection fraction. The mean serum level of vitamin D in patients on admission was 33. 62 ng/dL. The average number of hospitalization days was 4.8 days, and the rate of re-hospitalization was 26.6% in the six-month follow-up and 30.3% in the 9-month follow-up. The hospital mortality rate was equal to 1.4%, and the mortality rate at the end of the follow-up period was equal to 8.3%. The most common complication during hospitalization among the patients was ventricular tachycardia. However, in follow-up, re-hospitalization due to previous issues was the most common complication. Results: The mean serum vitamin D level was 33. 62 ng/ml,with 52.8% of patients having insufficient or deficient levels. The most common in-hospital complication was ventricular tachycardia (11.5%). Vitamin D deficiency was not significantly associated with in-hospital complications. However, during the follow-up period, vitamin D deficiency was significantly related to increased risk of readmission to hospital (HR: 6.984, 95% CI: 3.500-13.936, p&lt;0.001). The 6-month readmission rate was 26.6%, increasing to 30.3% at 9 months. Vitamin D deficiency was also associated with increased cardiac mortality (HR: 12.936, 95% CI: 1.494- 112.016, p=0.020) during follow-up. The 9-month mortality rate was 8.3%. Other factors contributing to cardiac mortality included disease severity (SYNTAX score) and female gender. Conclusions: While vitamin D deficiency did not impact short-term complications, it was associated with increased risk of hospitalreadmission and mortality in MI patients during medium-term follow-up. These findings suggest that vitamin D status can significantly impact long-term outcomes for MI patients

Applicability of Global Leadership Initiative on Malnutrition (GLIM) criteria in nutrition risk screening for patients over 60 years old with digestive system tumors – A retrospective study

ObjectiveThis study aimed to identify the most effective nutritional risk screening tool for elderly patients with digestive system tumors. MethodsNutritional risk screening was performed using Nutritional Risk Screening 2002 (NRS2002), prognostic nutritional index (PNI) and Geriatric Nutritional Risk Index (GNRI) for elderly patients who underwent surgical resection of digestive tumor. Comparative analysis of each nutritional screening tool was conducted through Kappa test and ROC curve. ResultsMalnourished individuals diagnosed by the Global Leadership Initiative on Malnutrition (GLIM) criteria had lower levels of hematological parameters (serum albumin, pre-albumin, total protein and hemoglobin) and poorer body composition parameters (body mass index, body fat percentage, edema index, upper arm muscle circumference, skeletal muscle index, and phase angle; P<0.05). NRS2002 demonstrated a sensitivity of 75.56% and specificity of 38.16% under the GLIM criteria, showing moderate agreement (Kappa=0.346, P<0.001). PNI had an average sensitivity of 71.11% and the highest specificity at 87.23%, but exhibited no consistency with GLIM (Kappa=0.152, P=0.062). GNRI showed the highest sensitivity at 91.11% and general specificity at 37.14%, aligning closely with GLIM criteria (Kappa=0.711, P<0.001). GNRI had the highest predictive value (AUC=0.870, 95% CI: 0.801–0.939), followed by NRS2002 (AUC=0.687, 95% CI: 0.589–0.785). Patients diagnosed with malnutrition via GNRI-GLIM exhibited higher rates of surgical site infection (χ2=15.534, P<0.001) and 3-month readmission (χ2=4.499, P=0.034). ConclusionGNRI and NRS2002 demonstrate good performance as GLIM criteria for nutritional screening in elderly patients with digestive tumors, with GNRI being potentially more suitable. Moreover, GNRI-GLIM can predict short-term prognosis in these patients.

Abstract We107: Reduction of Six-Month Heart Failure Readmission Rates in Patients Undergoing MitraClip with Beta Receptor Blockade

Introduction: MitraClip has been shown to reduce heart failure readmissions in patients with moderate to severe mitral valve regurgitation. Likewise, beta-blocker (BB) therapy has been shown to reduce morbidity and mortality in select heart failure patients. At the cellular level, chronic myocardial insult from ongoing heart failure and mitral regurgitation leads to persistent overstimulation of myocardial beta-receptors, ultimately reducing cardiac inotropic reserve and contributing to myocardial injury. Thus, we hypothesized that patients on beta-blocker therapy before the MitraClip procedure would have fewer heart failure-related readmissions. Hypothesis: We assessed the hypothesis that beta-blocker therapy before the MitraClip procedure would lead to fewer heart failure-related readmissions by conducting a retrospective cohort study. This would help us better understand the pathogenesis of re-admissions in this patient population as well as help us decide whether prophylactic initiation of BB therapy before the procedure would reduce the risk of heart failure readmissions. Methods: We reviewed the records of patients who underwent the MitraClip procedure at our institution from January 2017 to July 2022. Patients without listed home medications, as well as non-heart failure-related readmissions and deaths, were excluded. Patients were split into those on BB therapy and those with no BB therapy. Of the 401 charts screened, 324 met the inclusion criteria. Results: From those who met the inclusion criteria, 226 patients were on beta-blocker therapy, while 98 patients were not. Of those who had at least one heart failure-related readmission within 6 months of the MitraClip procedure, 18 patients were on beta-blocker therapy and 16 patients were not. Meaning a 7.96% readmission rate for patients on beta-blocker therapy, and a 16.32% readmission rate for those who were not (OR 2.05, 95% CI: 1.004 to 4.186, p&lt;0.05), with the number needed to treat being 11.9. Conclusions: Our data shows that the use of beta-blocker therapy was associated with a statistically significant decrease in 6-month heart failure readmissions in those undergoing the MitraClip procedure. This suggests that at the cellular level, cardiac beta receptor dysfunction plays an integral part in future hospitalizations in this population. In conclusion, beta-blocker therapy should be considered in heart failure patients planning to undergo the MitraClip procedure to reduce heart failure-related readmissions.

Study on the management effect of chronic disease intelligent information management platform in post percutaneous coronary intervention patients.

In 2019, approximately 330 million individuals in China were affected by cardiovascular diseases, with 11.4 million cases specifically attributed to coronary artery disease (CAD). A national public health report indicated that the mortality rate for CAD ranged from 121.59 to 130.14 per 100,000 individuals in 2019. The treatments for CAD include lifestyle changes, medications, percutaneous coronary intervention (PCI) and coronary artery bypass grafting. To investigate the management effect of a digital health program in patients with coronary artery disease (CAD) after percutaneous coronary intervention (PCI). This retrospective study compares blood pressure, blood glucose, low-density lipoprotein cholesterol (LDL-C), medication adherence, lifestyle modification, and readmission rate between digital health users and traditional follow-up in post-PCI CAD patients. In this study of 698 CAD patients, the 6-month readmission rate of all patients was 27.4%, with digital health users showing lower rates than those in traditional follow-up (22.6% vs. 32.1%, p= 0.005). Digital health users had significantly higher target achievements rates in blood pressure (79.7% vs. 54.7%, p< 0.001), blood glucose (98.9% vs. 82.5%, p< 0.001) and LDL-C level (71.3% vs. 52.7%, p< 0.001) at 6-month post-PCI. The digital health group had more patients adopting lifestyle changes, including quitting smoking, maintaining a healthy diet, and exercising regularly. In risk factor analysis, digital health utilization (OR = 0.60, 95%CI: 0.40-0.90, p= 0.014) and multivessel disease (double: OR = 1.72, 95%CI: 1.09-2.72, p= 0.02; triple: OR = 2.59, 95%CI: 1.61-4.17, p< 0.001) were independent predictors of CAD-related cardiovascular readmissions. Post-PCI patients using digital health platforms exhibited improved blood pressure, glucose, and LDL-C control, greater treatment adherence, enhanced lifestyle changes, and reduced six-month readmission rates versus those with traditional follow-up.

Clinical outcomes of nurse-coordinated interventions for frail older adults discharged from hospital: A systematic review and meta-analysis.

To determine the effects of nurse-coordinated interventions in improving readmissions, cumulative hospital stay, mortality, functional ability and quality of life for frail older adults discharged from hospital. Systematic review with meta-analysis. A systematic search using key search terms of 'frailty', 'geriatric', 'hospital' and 'nurse'. Covidence was used to screen individual studies. Studies were included that addressed frail older adults, incorporated a significant nursing role in the intervention and were implemented during hospital admission with a focus on transition from hospital to home. This review searched MEDLINE (Ovid), CINAHL (EBSCO), PubMed (EBSCO), Scopus, Embase (Ovid) and Cochrane library for studies published between 2000 and September 2023. Of 7945 abstracts screened, a total 16 randomised controlled trials were identified. The 16 randomised controlled trials had a total of 8795 participants, included in analysis. Due to the heterogeneity of the outcome measures used meta-analysis could only be completed on readmission (n = 13) and mortality (n = 9). All other remaining outcome measures were reported through narrative synthesis. A total of 59 different outcome measure assessments and tools were used between studies. Meta-analysis found statistically significant intervention effect at 1-month readmission only. No other statistically significant effects were found on any other time point or outcome. Nurse-coordinated interventions have a significant effect on 1-month readmissions for frail older adults discharged from hospital. The positive effect of interventions on other health outcomes within studies were mixed and indistinct, this is attributed to the large heterogeneity between studies and outcome measures. This review should inform policy around transitional care recommendations at local, national and international levels. Nurses, who constitute half of the global health workforce, are ideally situated to provide transitional care interventions. Nurse-coordinated models of care, which identify patient needs and facilitate the continuation of care into the community improve patient outcomes. Review findings will be useful for key stakeholders, clinicians and researchers to learn more about the essential elements of nurse-coordinated transitional care interventions that are best targeted to meet the needs of frail older adults. When frail older adults experience transitions in care, for example discharging from hospital to home, there is an increased risk of adverse events, such as institutionalisation, hospitalisation, disability and death. Nurse-coordinated transitional care models have shown to be a potential solution to support adults with specific chronic diseases, but there is more to be known about the effectiveness of interventions in frail older adults. This review demonstrated the positive impact of nurse-coordinated interventions in improving readmissions for up to 1 month post-discharge, helping to inform future transitional care interventions to better support the needs of frail older adults. This systematic review was reported in accordance with the Referred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. No Patient or Public Contribution.

Study protocol for evaluating the efficacy of early pulmonary rehabilitation combined with an internet-based patient management model in patients with COPD: a practical, multicentre, randomised controlled study from China.

COPD, a preventable and treatable disease, is characterised by persistent respiratory symptoms and airflow limitations, with high incidence, disability, mortality and disease burden. Currently, drug treatments mainly include bronchodilators and glucocorticoids, which are used to alleviate symptoms and improve lung function. Traditional medical care models and patients' lack of understanding of the disease result in regular and long-term hospitalisations, affect patients' quality of life and cause a need to explore more effective comprehensive intervention plans. This study is designed as a multicentre, randomised controlled trial consisting of three parallel groups. Group A will receive early pulmonary rehabilitation in the hospital and remote internet pulmonary rehabilitation after discharge. Group B will receive the same early pulmonary rehabilitation in the hospital but outpatient pulmonary rehabilitation after discharge for 8 weeks and routine follow-up management. Group C will receive outpatient pulmonary rehabilitation during a stable period of 3-4 weeks after discharge and routine follow-up management. 1482 patients will be enrolled from 10 centres in China. The primary outcome measures will be the readmission rate due to acute exacerbation at 90 days and the 12-month readmission rate due to acute exacerbation. The secondary outcomes will mainly include differences in all-cause mortality; the number of acute exacerbations; COPD Assessment Test, modified Medical Research Council scale and St George's Respiratory Questionnaire scores; the pulmonary rehabilitation treatment completion rate; patient compliance; and patient and physician satisfaction scores among the three groups at 3, 6 and 12 months after the different interventions. In addition, the proportion of people with ≥2 acute exacerbations within 12 months and the time of the first acute exacerbation will also be included. This study aims to further verify the substitutability of remote internet pulmonary rehabilitation for outpatient rehabilitation and its short-term and long-term effects in patients, providing comprehensive interventional evidence for the treatment of COPD.

The burden of readmissions after rib fractures among older adults

BackgroundThe index hospitalization morbidity and mortality of rib fractures among older adults (aged ≥65 years) is well-known, yet the burden and risks for readmissions after rib fractures in this vulnerable population remain understudied. We aimed to characterize the burdens and etiologies associated with 3-month readmissions among older adults who suffer rib fractures. We hypothesized that readmissions would be common and associated with modifiable etiologies. MethodsThis survey-weighted retrospective study using the 2017 and 2019 National Readmissions Database evaluated adults aged ≥65 years hospitalized with multiple rib fractures and without major extrathoracic injuries. The main outcome was the proportion of patients experiencing all-cause 3-month readmissions. We assessed the 5 leading principal readmission diagnoses overall and delineated them by index hospitalization discharge disposition (home or facility). Sensitivity analysis using clinical classification categories characterized readmissions that could reasonably represent rib fracture-related sequelae. ResultsIn 2017, 25,092 patients met the inclusion criteria, with 20% (N = 4,894) experiencing 3-month readmissions. Six percent of patients did not survive their readmission. The 5 leading principal readmission diagnoses were sepsis (many associated with secondary diagnoses of pneumonia [41%] or urinary tract infections [41%]), hypertensive heart/kidney disease, hemothorax, pneumonia, and respiratory failure. In 2019, a comparable 3-month readmission rate of 23% and identical 5 leading diagnoses were found. Principal readmission diagnosis of hemothorax was associated with the shortest time to readmission (median [interquartile range]:9 [5–23] days). Among patients discharged home after index hospitalization, pleural effusion–possibly representing mischaracterized hemothorax–was among the leading principal readmission diagnoses. Some patients readmitted with a principal diagnosis of hemothorax or pleural effusion had these diagnoses at index hospitalization; a lower proportion of these patients underwent pleural fluid intervention during index hospitalization compared with readmission. On sensitivity analysis, 30% of 3-month readmissions were associated with principal diagnoses suggesting rib fracture-related sequelae. ConclusionReadmissions are not infrequent among older adults who suffer rib fractures, even in the absence of major extrathoracic injuries. Future studies should better characterize how specific complications associated with readmissions, such as pneumonia, urinary tract infections, and delayed hemothoraces, could be mitigated.

Sodium-Glucose Cotransporter Type 2 Inhibitors Use in Elderly Polypathological Patients with Acute Heart Failure: PROFUND-IC Registry.

Background/Objectives: Heart failure (HF) is a highly prevalent clinical syndrome with serious morbidity and mortality. Furthermore, acute heart failure (AHF) is the main cause of hospital admission in people aged 65 years or more. Sodium-glucose cotransporter type 2 inhibitors (SGLT2is) have been shown to improve the survival and quality of life in patients with HF regardless of left ventricular ejection fraction (LVEF). Our aims were to describe the characteristics of adults with multiple pathologies admitted with acute heart failure as the main diagnosis and of the population treated with SGLT2is, as well as to evaluate if their use was associated with lower readmission and mortality rates. Methods: A prospective study of patients from the PROFUND-IC registry who were admitted with AHF as the main diagnosis was conducted. Clinical and analytical characteristics were analyzed, as well as readmissions and mortality. Descriptive and bivariate analyses of the sample between those taking SGLT2is and those who were not were performed, using the chi-square test for qualitative variables and Welch's test for quantitative measures, as well as the Fisher and Wilcoxon tests as indicated for nonparametric tests. Kaplan-Meier curves were constructed to analyze the readmission and mortality of patients at 12 months based on SGLT2i treatment. Finally, a propensity score matching was performed, guaranteeing that the observed effect of the drug was not influenced by the differences in the characteristics between the groups. Results: There were 750 patients included: 58% were women, and the mean age was 84 years. Functional class II according to the NYHA scale predominated (54%), and the mean LVEF was 51%. SGLT2 inhibitors were prescribed to only 28% of patients. Most of the patients were men (48.6% vs. 39.8%, p = 0.029), they were younger (82 vs. 84 years, p = 0.002), and their LVEF was lower (48% vs. 52%, p < 0.001). Lower mortality was observed in the group treated with SGLT2is, both during baseline admission (2.4% vs. 6.9%, p = 0.017) and at the 12-month follow-up (6.2% vs. 13%, p = 0.023); as well as a lower readmission rate (23.8% vs. 38.9%, p < 0.001). After the propensity score matching, a decrease in the 12-month readmission rate continued to be observed in the group treated with SGLT2is (p = 0.03). Conclusions: SGLT2is use was associated with lower readmission rates at the 12-month follow-up in older adults with multiple pathologies admitted with acute heart failure.

Factors affecting 12-month unplanned readmissions for chronic obstructive pulmonary disease patients: the effect of mental disorders in an Australian cohort.

Many individuals with chronic obstructive pulmonary disease (COPD) experience frequent hospitalization and readmissions, which is burdensome on the health system. This study aims to investigate factors associated with unplanned readmissions and mortality following a COPD-related hospitalization over a 12-month period in Australia, focusing on mental disorders and accounting for the acute phase of the COVID-19 pandemic. A retrospective cohort study using linked hospitalization and mortality records identified individuals aged ≥40years who had at least one hospital admission with a principal diagnosis of COPD between 2014 and 2020 in New South Wales, Australia. A semi-competing risk analysis was conducted to examine factors associated with unplanned readmission and mortality. Adults with a mental disorder diagnosis, specifically anxiety, had a higher risk of 12-month unplanned readmission. Individuals with anxiety and dementia also had a higher risk of mortality pre- and post-unplanned readmission. Individuals who were admitted during the acute phase of the COVID-19 pandemic period had lower risk of unplanned readmission, but higher risk of mortality without unplanned readmission. Interventions aimed at reducing admissions should consider adults living with mental disorders such as anxiety or dementia to improve healthcare delivery and health outcomes for individuals living with COPD.

Liposomal Bupivacaine Analgesia in Deep Inferior Epigastric Perforator Flap Breast Reconstruction: A Retrospective Cohort Study

Background: Liposomal bupivacaine (LB) can be used for postsurgical analgesia after breast reconstruction. We examined real-world clinical and economic benefits of LB versus bupivacaine after deep inferior epigastric perforator (DIEP) flap breast reconstruction. Methods: This retrospective cohort study used the IQVIA claims databases to identify patients undergoing primary DIEP flap breast reconstruction in 2016–2019. Patients receiving LB and those receiving bupivacaine were compared to assess opioid utilization in morphine milligram equivalents (MMEs) and healthcare resource utilization during perioperative (2 weeks before surgery to 2 weeks after discharge) and 6-month postdischarge periods. A generalized linear mixed-effects model and inverse probability of treatment weighting method were performed. Results: Weighted baseline characteristics were similar between cohorts (LB, n = 669; bupivacaine, n = 348). The LB cohort received significantly fewer mean MMEs versus the bupivacaine cohort during the perioperative (395 versus 512 MMEs; rate ratio [RR], 0.771 [95% confidence interval (CI), 0.677–0.879]; P = 0.0001), 72 hours after surgery (63 versus 140 MMEs; RR, 0.449 [95% CI, 0.347–0.581]; P &lt; 0.0001), and inpatient (154 versus 303 MMEs; RR, 0.508 [95% CI, 0.411–0.629]; P &lt; 0.0001) periods; postdischarge filled opioid prescriptions were comparable. The LB cohort was less likely to have all-cause inpatient readmission (odds ratio, 0.670 [95% CI, 0.452–0.993]; P = 0.046) and outpatient clinic/office visits (odds ratio, 0.885 [95% CI, 0.785–0.999]; P = 0.048) 3 months after discharge than the bupivacaine cohort; other all-cause healthcare resource utilization outcomes were not different. Conclusions: LB was associated with fewer perioperative MMEs and all-cause 3-month inpatient readmissions and outpatient clinic/office visits than bupivacaine in patients undergoing DIEP flap breast reconstruction.

#2334 Elevated serum admission creatinine in acute heart failure hospitalizations: lifting the veil to understand outcome differences

Abstract Background and Aims Organ crosstalk in heart failure and kidney dysfunction is prevalent and is associated to a high event rate. In this setting elevated serum creatinine (sCr) at acute decompensated heart failure (ADHF) admissions is a strong risk factor for poor outcomes. Current accepted cardiorenal syndrome (CRS) classification is based on timing and initial organ dysfunction and fails at capturing its nature and prognosis. We sought to describe patient (P) profile and outcomes in P hospitalized for ADHF with high admission sCr in function of current CRS classification and assess for stratifying predictors. Method We conducted an observational, analytical and cross-sectional study, with prospective and consecutive data acquisition. We included P over 18 years-old, who were admitted to the Intensive Care Telemetry Unit in our Hospital between July, 2011 and Dec, 2023 due to ADHF. P who received a heart transplant during index admission or those on chronic dialysis were excluded. Clinical, epidemiological and biochemical variables were registered. Renal dysfunction was defined under admission sCr &amp;gt;1.4 mg/dl and divided according to Ronco et al classification, as initially cardiac (type 2) or renal (type 4) origin. We constructed multivariate logistic and survival regression models, with selection of relevant predictors by resampling and regularization of a Lasso regression model. Statistical significance was considered with a 5% of alpha error level. Analysis was conducted using R (R Core Team, 2023). Results A total of 1868 consecutive P were included. P population consisted in type 2: 124 and type 4: 258 P, respectively. We found no differences in gender (p = 0.47), while type 4 were older (75 ± 12 vs 71 ± 12; p &amp;lt; 0.01). Ventricular dysfunction was more severe in type 2 (left ventricular ejection fraction 34 ± 17 vs 41 ± 16%; p &amp;lt; 0.001). While ischaemic heart disease was more prevalent in type 4 (32.8 vs 23.5%; p = 0.001), idiopathic cardiomyopathy was more frequent in type 2 (18.8 vs 7.2%; p = 0.001). Clinical phenotypes differed between groups, being clinical hypoperfusion more frequent in type 2 (32.4 vs 12.3%; p &amp;lt; 0.001). Admission sCr was higher in type 4 (1.9 [0.8] vs 1.6 [0.58] mg/dl; p &amp;lt; 0.001), as was 1st day natriuresis (81 vs 67 mEq; p = 0.01). Both groups experienced a similar diuretic resistance rate (21.2 vs 17.1%; p = 0.34), while type 4 received rescue ultrafiltration more frequently (11.3 vs 3.5%; p &amp;lt; 0.01). Type 2 received a higher inotropic support rate (47.1 vs 19.5%; p &amp;lt; 0.01) and had a longer length of stay (9 vs 7 days; p = 0.01). In-hospital (11.8 vs 11.3%; p = 0.99); 6-month and 1-year mortality rates (66.8 vs 72.8% and 55.1 vs 64.6% respectively; p = 0.3). In a similar way, 1-month (94.8 vs 94.7%), 6-month (72 vs 74.7%) and 1-year readmission rates (59.2 vs 60.9%; p = 0.6) were similar in both groups. A multiple logistic regression model (AUCROC 0.82) identified admission sCr (OR 2.6; CI 95% 2.2-3.2; p &amp;lt; 0.001), inotropic need (OR 1.87; CI 95% 1.4-2.6; p &amp;lt; 0.001), anasarca phenotype (OR 1.63; CI 95% 1.06-2.5; p = 0.02), moderate to severe right ventricular dysfunction (OR 1.4; CI 95% 1.03-1.9; p = 0.03) as independent predictors for a descending sCr behavior during hospitalization, while the lower T3 levels were associated with less probability for a descent of sCr (OR 0.21; CI 95% 0.1-0.46; p &amp;lt; 0.001). Conclusion Organ crosstalk in ADHF hospitalizations was associated with a high event rate. One-year mortality and readmission rates were similar in both groups. Renal support therapies were more frequent under lower kidney reserve conditions. Ventricular dysfunction and systemic congestion phenotype are relevant to a better understanding for potential reversibility at the admission time and may promote actions for outcome enhancing.

A Cost–Consequence Analysis of Nutritional Interventions Used in Hospital Settings for Older Adults with or at Risk of Malnutrition

Background: Malnutrition is a significant and prevalent issue in hospital settings, associated with increased morbidity and mortality, longer hospital stays, higher readmission rates, and greater healthcare costs. Despite the potential impact of nutritional interventions on patient outcomes, there is a paucity of research focusing on their economic evaluation in the hospital setting. This study aims to fill this gap by conducting a cost–consequence analysis (CCA) of nutritional interventions targeting malnutrition in the hospital setting. Methods: We performed a CCA using data from recent systematic reviews and meta-analyses, focusing on older adult patients with or at risk of malnutrition in the hospital setting. The analysis included outcomes such as 30-day, 6-month, and 12-month mortality; 30-day and 6-month readmissions; hospital complications; length of stay; and disability-adjusted life years (DALYs). Sensitivity analyses were conducted to evaluate the impact of varying success rates in treating malnutrition and the proportions of malnourished patients seen by dietitians in SingHealth institutions. Results: The CCA indicated that 28.15 DALYs were averted across three SingHealth institutions due to the successful treatment or prevention of malnutrition by dietitians from 1 April 2021 to 31 March 2022, for an estimated 45,000 patients. The sensitivity analyses showed that the total DALYs averted ranged from 21.98 (53% success rate) to 40.03 (100% of malnourished patients seen by dietitians). The cost of implementing a complex nutritional intervention was USD 218.72 (USD 104.59, USD 478.40) per patient during hospitalization, with additional costs of USD 814.27 (USD 397.69, USD 1212.74) when the intervention was extended for three months post-discharge and USD 638.77 (USD 602.05, USD 1185.90) for concurrent therapy or exercise interventions. Conclusion: Nutritional interventions targeting malnutrition in hospital settings can have significant clinical and economic benefits. The CCA provides valuable insights into the costs and outcomes associated with these interventions, helping healthcare providers and policymakers to make informed decisions on resource allocation and intervention prioritization.

Baseline 25(OH)D level is a prognostic indicator for bariatric surgery readmission: a matched retrospective cohort study.

Managing postsurgical complications is crucial in optimizing the outcomes of bariatric surgery, for which preoperative nutritional assessment is essential. In this study, we aimed to evaluate and validate the efficacy of vitamin D levels as an immunonutritional biomarker for bariatric surgery prognosis. This matched retrospective cohort study included adult patients who underwent bariatric surgery at a tertiary medical center in China between July 2021 and June 2022. Patients with insufficient and sufficient 25(OH)D (< 30 ng/mL) were matched in a 1:1 ratio. Follow-up records of readmission at 3 months, 6 months, and 1 year were obtained to identify prognostic indicators. A matched cohort of 452 patients with a mean age of 37.14 ± 9.25 years and involving 69.47% females was enrolled. Among them, 94.25 and 5.75% underwent sleeve gastrectomy and gastric bypass, respectively. Overall, 25 patients (5.54%) were readmitted during the 1-year follow-up. The prognostic nutritional index and controlling nutritional status scores calculated from inflammatory factors did not efficiently detect malnourishment. A low 25(OH)D level (3.58 [95% CI, 1.16-11.03]) and surgery season in summer or autumn (2.68 [95% CI, 1.05-6.83]) increased the risk of 1-year readmission in both the training and validation cohorts. The area under the receiver operating characteristic curve was 0.747 (95% CI, 0.640-0.855), with a positive clinical benefit in the decision curve analyses. The relationship between 25(OH)D and 6-month readmission was U-shaped. Serum 25(OH)D levels have prognostic significance in bariatric surgery readmission. Hence, preferable 25(OH)D levels are recommended for patients undergoing bariatric surgery.

Internet of Things-Based Home Respiratory Muscle Training for Patients with Chronic Obstructive Pulmonary Disease: A Randomized Clinical Trial.

Whether Internet of Things (IoT)-based home respiratory muscle training (RMT) benefits patients with comorbid chronic obstructive pulmonary disease (COPD) remains unclear. Therefore, this study aims to evaluate the effectiveness of IoT-based home RMT for patients with COPD. Seventy-eight patients with stable COPD were randomly divided into two groups. The control group received routine health education, while the intervention group received IoT-based home RMT (30 inspiratory muscle training [IMT] and 30 expiratory muscle training [EMT] in different respiratory cycles twice daily for 12 consecutive weeks). Assessments took place pre-intervention and 12 weeks post-intervention, including lung function tests, respiratory muscle strength tests, the mMRC dyspnea scale, CAT questionnaires, the HAMA scale, and 6-month COPD-related readmission after intervention. Seventy-four patients with COPD were analyzed (intervention group = 38, control group = 36), and the mean age and FEV1 of the patients were 68.65 ± 7.40 years, 1.21 ± 0.54 L. Compared to those of the control population, the intervention group exhibited higher FEV1/FVC (48.23 ± 10.97 vs 54.32 ± 10.31, p = 0.016), MIP (41.72 ± 7.70 vs 47.82 ± 10.99, p = 0.008), and MEP (42.94 ± 7.85 vs 50.29 ± 15.74, p = 0.013); lower mMRC (2.00 [2.00-3.00] vs 1.50 [1.00-2.00], p < 0.001), CAT (17.00 [12.00-21.75] vs 11.00 [9.00-13.25], p < 0.001), and HAMA (7.00 [5.00-9.00] vs 2.00 [1.00-3.00], p < 0.001) scores; and a lower incidence rate of 6-month readmission (22% vs 5%, p = 0.033). Compared with no intervention, IoT-based home RMT may be a more beneficial intervention for patients with COPD.

A randomized controlled trial of a postdischarge nursing intervention for patients with decompensated cirrhosis.

Few randomized trials have evaluated the effect of postdischarge interventions for patients with liver cirrhosis. This study assessed the effects of a postdischarge intervention on readmissions and mortality in patients with decompensated liver cirrhosis. We conducted a randomized controlled trial at a specialized liver unit. Adult patients admitted with complications of liver cirrhosis were eligible for inclusion. Participants were allocated 1:1 to standard follow-up or a family-focused nurse-led postdischarge intervention between December 1, 2019, and October 31, 2021. The 6-month intervention consisted of a patient pamphlet, 3 home visits, and 3 follow-up telephone calls by a specialized liver nurse. The primary outcome was the number of readmissions due to liver cirrhosis. Of the 110 included participants, 93% had alcohol as a primary etiology. We found no significant differences in effects in the primary outcomes such as time to first readmission, number of patients readmitted, and duration of readmissions or in the secondary outcomes like health-related quality of life and 6- and 12-month mortality. A post hoc exploratory analysis showed a significant reduction in nonattendance rates in the intervention group (RR: 0.28, 95% CI: 0.13-0.54, p=0.0004) and significantly fewer participants continuing to consume alcohol in the intervention group (p=0.003). After 12 months, the total number of readmissions (RR: 0.76, 95% CI: 0.59-0.96, p=0.02) and liver-related readmissions (RR: 0.55, 95% CI: 0.36-0.82, p=0.003) were reduced in the intervention group. A family-focused postdischarge nursing intervention had no significant effects on any of the primary or secondary outcomes. In a post hoc exploratory analysis, we found reduced 6-month nonattendance and alcohol consumption rates, as well as reduced 12-month readmission rates in the intervention group.

Association of lactate/albumin ratio with 3-month readmission risk in heart failure patients: a retrospective study.

The predictive value of the lactate/albumin ratio (LAR) in mortality is established in various conditions, yet its relevance to 3-month readmission risk in Chinese adults with heart failure (HF) remains unclear. Analysing data from 957 patients with HF at Zigong Fourth People's Hospital, Sichuan, China (December 2016 to June 2019), we assessed baseline characteristics, vital signs, comorbidities, and prescriptions. LAR demonstrated a linear correlation with 3-month readmission risk (HR=1.60, 95% CI: 1.19-2.16). Tertile 3 (≥-0.48) exhibited higher risk than tertile 1 (<-0.83) and tertile 2 [-0.83, -0.48), with HRs and 95% CI of 1.49 (1.06-2.10), 1.43 (1.01-2.02), 1.48 (1.03-2.12), respectively. Subgroup and sensitivity analyses affirmed consistent influence of LAR on 3-month readmission risk for HF. Higher LAR significantly correlates with increased 3-month readmission risk in Chinese adult patients with HF, suggesting LAR is a valuable predictor for early readmission.
